When it comes to acoustic guitar strings, the material used for the winding plays a critical role in shaping the tone, playability, and overall experience of the instrument. Among the most popular string materials in the market, copper alloy and phosphor bronze stand out for their distinct tonal characteristics and performance advantages.
The winding material on acoustic strings significantly affects tone color and response. Whether you're aiming for crisp brightness or mellow warmth, the right choice of string material can make all the difference.
At Alice, we manufacture both copper alloy and phosphor bronze acoustic strings using advanced production technologies and strict quality control. Let’s look at what makes each material unique.
Copper alloy strings are crafted with a steel hexagonal core and a copper-based winding material. They are often characterized by their golden appearance and vibrant tone.
Bright and clear with a sharp attack
Excellent projection and articulation
Ideal for strumming and percussive fingerstyle
Especially suitable for live performance and pop/folk genres
Our A206 Series acoustic strings are made with copper-plated alloy winding and anti-rust coating, designed for players who demand brilliance and responsiveness. The A206 line provides a crisp tone with great string balance, and is available in multiple gauges to suit different playing needs.
Phosphor bronze is a copper-tin alloy with a small percentage of phosphorus added. It’s known for producing a warmer, richer tone with longer sustain.
Warm and mellow with balanced harmonics
Smooth tone ideal for fingerpicking and accompaniment
Enhanced durability and corrosion resistance
Great for recording, singer-songwriter, and traditional acoustic music
The AWR486 Series strings are built with a hexagonal steel core and precision-wound phosphor bronze wrap. Designed for tonal warmth and longevity, this series is a favorite among players who prefer a more rounded and natural acoustic sound.

Choosing between copper alloy and phosphor bronze strings depends on your guitar, playing style, and tonal preference:
For a brighter tone and enhanced projection, especially on darker-sounding guitars, copper alloy strings like the A206 Series will bring out sparkling highs and energetic mids.
For a warmer, fuller sound with a natural acoustic feel, especially on brighter guitars, phosphor bronze strings like the AWR486 Series offer smooth response and tonal richness.
If you're unsure, we encourage you to try both and hear the difference for yourself. Many guitarists even use different string types for different musical projects or environments.
